Abstract
Two-dimensional ferromagnet K 2CuF 4 is an ideal compound to study two-dimensional magnetic systems because the interplane exchange coupling constant is much smaller than the intraplane exchange coupling constant. We measured the temperature dependence of the NMR frequencies of the 1 2 ↔ 3 2 transition for 63 Cu and 65 Cu nuclei in K 2CuF 4 single crystal far below T c =6.25 K . The NMR measurements were made by spin-echo method at zero magnetic field. The experimental results are discussed in the framework of the two-dimensional spin wave theory at millikelvin temperatures.
